title: [Hemoglobin, serum iron and transferrin saturation among users of intrauterine devices and oral contraceptive agents].
abstract: We studied 60 females using either intrauterine device or taking oral contraceptive pills. Hemoglobin, serum iron, total iron binding capacity and saturation of transferrin were determined before and 4 and 10 months after starting a responsible paternity program. Women with a basal hemoglobin level below 12 g/dl were excluded. Age, parity and hematologic parameters were similar for both groups. A significant decrease in hemoglobin level and saturation of transferrin was observed at 10 months in intrauterine device users (13.6 to 13.1 g/dl and 36.2 to 26.9%, respectively). Use of oral contraceptive pills was not associated to hemoglobin decrease but a significant rise in saturation of transferrin was observed (36.2 to 43.9%, p less than 0.05).
